.Application filed September 15, 1930. Serial No. 482,107.

The present invention relates to binding posts for electrical apparatus of various kinds, and contemplates a novel construction to effect a quick and positive contact with the i conductor terminal.

In accordance with the present invention I provide a yieldably supported binding post having a lcontact head constructed and arranged to receive the wire and effectively clamp the same therebetween and the cooperating fixed contact of the apparatus,

Another object of the invention resides in the provision of a binding post of the abovementioned character, Vwherein the head is 'l5 formed with a normally offset portion to facilitate lifting of the binding post by a suitable tool, when it is desired to either attach or remove the terminal of the conductor wire.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed. f l

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a fragmentary plan view of an electrical apparatus illustrating the invention.

Figure 2 is a vertical sectional View taken through Figure 1.

Figure 3 is an enlarged fragmentary sectional view showing the contact head of the binding post in edge elevation.

Figure 4 is a view similar to Figure 3 showing the binding post partly in section, 10 and also illustrating how the contact head kcan be removed from the fixed Contact by means of a suitable tool.

It is of course understood that the present invention has reference to a binding post per se, and is capable of being used wherever1 such posts are desired. I have illustrated the invention vin conection with an electrical apparatus including a base 10 upon which is mounted the usual bracket 11 for the mov- 59 able element 12 of a switch, while projecting from the bracket 11 is the usual fixed contact 13 which reposes upon the base 10. Y The fixed contact 13 has a .central opening through which the shank of the binding post isy passed, while the base 10 is vprovided with, a large 55 recess 14 to receive/the shank, which' recess is sealed in any' suitable manner from its bottomasat 15. y Y `l T he binding post itselfcomprises a shank 16 which carries at itsupper enda 'disk-like GG contact head 17 the latter being slotted from its center'toward its .edgev as at 18, while a portion of the head at one side of this slot is oifset upwardly as at 19 for a purpose to be presently described. As above stated the G5 shank 1G is passed through the fixed contact 13 and is received by the recess 14 of the base, and has-associated with its lower end a nut 20. Surrounding the shank is a coiled spring 21, one end of which bears against 7@- the upper wall of the recess, while its lower end engages the nut 20, thereby yieldably supporting the binding post in its entirety in a manner to eiiect both a quick and positive contact with the conductor terminal wire Upon inspection of Figure 4 it will be noted that the contact head 17 normally reposes upon the fixed contact 13, and when it is desired to attach the conductor terminal wire 22 to the binding post, the latter can be quickly and easily raised against the iniiuence of the spring 21 by means of a suitable tool 23. This tool can be arranged beneath the oiset portion 19 of the Contact head 85 17 for this purpose, and when the head 17 is spaced from the xed contact 13 the conductor wire can be quickly associated with or removed from the binding post as the occasion may require. 'The conductor terminal 90 wire 22 has its free'end offset as at 24, and this offset extremity is first positioned within the slot 18ct the contact head 17, after which the wire is coiled about the binding post as illustrated, and when the tool 23'is removed, Y 95v and the binding post released therefrom, the coil spring 20 quickly moves the contact head 17 into clamping relation with the xed contact 13, thereby immovably holding the conductor terminal wire 23 between said parts. 100

By positioning the offset extremity 24 of the conductor terminal wire in the slot 18, the Wire is not only eiectively clamped to the binding post, but the wire is also prohibited from turning with relation to the post as will be readily understood.

While itis believed that from `,the foregoing description ithe nature :and @advantages of the invention will be readily understood, I desire to have it known that I do notlimi't myself to what is herein illustrated .and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim as new is:

n The, combination with -a supporting base having ia fixed Contact thereon, of a binding post yincluding a shank slidably received by said hase, 'and a Contact head having a slot adapted to receive an offset extremity of a terminal conductor wire coiled about said shank, a yieldable means for effectively clamping the wir-e between the contact head and .said fixed contact, and a portion of the contact head at one side of thenslot being oil'set outwardly for the purpose specified..

In .testimony whereof, IaiiX my signature.

EARL D. PELTON.
